Yes. Remove any ridges from wear and grease them up. Later springs had a channel and a zerk for grease.
I've used poly liner on leaf springs for over 30 years. Don't make noise and give consistent compression and rebound. Also have never worn out the liners and have put them on all my leaf spring vehicles.
40's and 50's Chevys are wrapped in lead. that stuff holds the grease. I think grease is good. I think I'd leave it if I had a choice.
Ok cool I just put another coat of paint on, one more to go. Ill look in to packing tomry when the shops open.
Grease also attracks dirt...get dirt in the grease and it'll slowly eat your springs away. If you wanna grease em, you gotta wrap em good as well.
Well it looks like im staying away from grease because this is a rear model a spring and iv dressed up the ends of each leaf so this will be unwrapped. Im down to poly liner unless the graphite holds back the dirt in the grease. lots of good ones if anyone has a tip feel free. Thanks
